Information on Result #3148885

There is no digital (48, 200, 200)-net over F₄, because 8 times m-reduction would yield digital (48, 192, 200)-net over F₄, but

extracting embedded orthogonal array [i] would yield linear OA(4¹⁹², 200, F₄, 144) (dual of [200, 8, 145]-code), but
- constructionÂ Y1 [i] would yield
  1. linear OA(4¹⁹¹, 196, F₄, 144) (dual of [196, 5, 145]-code), but
    - residual code [i] would yield linear OA(4⁴⁷, 51, F₄, 36) (dual of [51, 4, 37]-code), but
      - a result by Landjev, Maruta, and Hill [i]
  2. OA(4⁸, 200, S₄, 4), but
    - discarding factors would yield OA(4⁸, 121, S₄, 4), but
      - the Rao or (dual) Hamming bound shows that MÂ â‰¥ 65704 > 4⁸ [i]

Mode: Bound (linear).
